Self-Regulating Heating Cable


ZMS provides a self-regulating heating cable that automatically adjusts its output power to compensate for temperature changes. It is suitable for various industrial, commercial and residential applications. Our heating cables meet the needs of most applications, including process temperature maintenance, anti-freeze protection of pipes, extension cord heating, anti-frost heave and more.

What is a self-regulating heating cable?

The power of a self-regulating heating cable will increase as the temperature decreases, and decrease as the temperature increases. Self-regulating heating cables use variable resistance carbon-based heating elements. And it is a parallel structure that can output power along its length to suit local conditions.

Specifically, you need to understand how the cable works before the cable is selected.

The self-regulating heating cable of the electric heating element is in the two parallel metal busbars uniformly extruded between a layer of PTC material made of core tape. PTC material by the melt extrusion, cooling and shaping, and dispersion of carbon particles in the formation of a myriad of fine conductive carbon networks. When they are connected across two parallel busbars, it constitutes the PTC parallel circuit of the core tape. When the two busbars at one end of the cable are connected to the power supply, the current flows laterally from one busbar through the PTC material layer to the other busbar to form a parallel circuit.

The PTC layer is the resistance heat generator continuously connected in parallel between the busbars, which converts the electric energy into heat energy and accompanies the heat insulation for the operating system. When the temperature of the core belt rises to the corresponding high resistance area, the resistance is so large that it almost blocks the current, and the temperature of the core belt will reach the high limit and will not rise anymore (i.e., automatically temperature limitation). At the same time, the core belt through the sheath to the lower temperature of the heated system heat transfer, to reach a steady state when the heat transferred per unit of time is equal to the cable’s electrical power. The power output of the cable is mainly controlled by the heat transfer process and the temperature of the heated system.

The function of our self-adjusting heating cable is the same as that of foreign Thermo BSX 8-2-FOJ Raychem BTV. Our heating cables have the following characteristics:
